The company, BCC was aquired by eStorage. Much like the ocean, where fish eat each other all of the time, eStorage got aquired by Zzyzx peripherals. The web address, http://www.estorageinc.com will still get you to the place you want.
Meanwhile, I’ve got some used “estorage” DASD on the shelf, up for sale. I’m not sure if that’s an appropriate use of this forum, so I’m omitting the details. It may or may not be the kind of disk you need or want. If you’re curious, contact me for details via the forum and we figure out how to contact each other.
